Awesome. I deleted the old install and reinstalled through the app store. The Doghouse menu is there, it's registered AND it kept my libraries intact so... bonus.
I selected a few albums that didn't show up in a Doghouse search and selected "Contribute Selection". Once I see that they are showing up correctly in a Doghouse search, I'll start submitting more.
Sweet... my contributions show up in the Doghouse search now!
